To all whom it may concern Be it known that I, JUST N KAY ToLns, a citizen'of the United States f'America, re:-' siding at San Francisco, countyof San Fran-J cisco, State of California, haveinvented a certain new and useful IFiberaCleaning Ap ing to be a full, clear, and exactdescription of the invention, such as will enable others. skilled in the art to'which it appertains to make and use the same.

This invention relates to fiber cleaning apparatus, and it may be said to consist. in the provision of the novel and advantageous features and in the novel and improved'construction, arrangement and combination of parts and devices as willbe apparent from the description and claims which follow hereinafter.

One object of the inventionis to provide novel and improved means for guiding the fibrous material throughthe apparatus from the intake end to the discharge end of the apparatus. i i Another object of the invention is to provide novel and improved means for causing the fibrous material to follow a definite course through the apparatus. l

A further object of the invention is to provide novel and improved means whereby. the fibrous material while being treated in the apparatus is constrained to proceed in a A further object, of theinv ention is to pro-.:

narily cleaning a portion ofthe fibrousmaterial as the latter is being fedinto the .ap-

paratus. p

A further object of the invention is to provide a novel and improved stationary device which surrounds the rotor and is adapted to guide the fibrous materialiandtocoact with the rotor to clean the fibrous material.

Further objects of the invention are to provide apparatus ofthe class specified, which is simple in character, economical to construct, maintain, and use, easy to operate, strong and durable, positive and certain in its action, efiicient in servicegproduceslong fiber, and which is generallysuperior and better 1 from :a commercial standpoint than existing apparatus of this class.

insuitable. bearings '23 and has thereon the are mounted fast .on theshaft, 22,- and a plurality ofspaced inclined timbers 26 havfing thereon plates 27 are secured on -the periphery of the spiders 25 by means of i I rods 28v which pass through the plates and the plates 27 and driven into the timbers 26. j

The pins .30 may be disposed staggered in 1 one or more rows on thezplates 27, and are junctionofi diverging aces 32, preferably 'SH H the OtOI" 21 is constructed as? follows; '{Ijh "shaft 22is: rotatably mounted fpresent the edge of a Vshape, to the material passing through 10,

rotated the ends of the pins 30 pass close to the ends of and substantially in alinement with the pins 33. Curved plates or vanes 34 are disposed between the timbers 26 and they may have the edges thereof suitably secured to the plates 27. The rotor 21 is ar ranged within a casing 35 which latter is preferably formed of metal and has therein a framework 36 to which is suitably secured timbers 37 having aliixed thereon the pins 33.

On the framework 36 is mounted a .sta tionary cage 38 which surrounds the rotor 21 and which is formed to provide a longitudinal recess 39 therein, preferably in the upper rear part thereof, and which has thereon means to guide the fibrous material and also means adapted to scrape and clean the fibrous material in coaction with the rotor 21. As shown, the cage 38 is preferably formed of spaced lower substantially semi-circular bars 40 having one end thereof joined to substantially vertical bars 41 and having the other end thereof joined to bars 42 which latter are formed with a circular portion 43 adjacent to the bars 40 and with a horizontal portion 44 adjacent to the vertical bars 41, tie rods 45 passing through the bars 40, 41, and 42, and preferably rectangular scraping bars 46 mounted on the bars '40, 41, and 42. As seen more clearly inFig. 7 the bars 40 and 42 are arranged to have their junction with each other-at the front of the cagesubstantially midway between their junction with the vertical bars 41-at the rear of the cage-whereby they constitute a substantially helical guide for the fibrous material from the inlet opening 47 to a point adjacent to the discharge opening 48 where they may be arranged parallel and in vertical alinement. The bars 40 may be joined to the bars 4l'and 42 by means of strips 49 extending into grooves in the bars 41 and 42, and bolts 50 which pass through the strips 49 and are secured by nuts 51 to the angle irons 52 affixed to the timbers 37; also the bars 40 and 42 may have thereon strips 53 which are connected by bolts 54 to the I-beams 55 which latter may be secured to the framework 36 and to the ends of the casing 35.

At an opening 56 in the casing 35 adjacent to the intake opening 47 in the cage 38, are arranged a pair of suitable spring-pressed grip rollers 57 at the rear end of a suitable conveyer 58 for feeding the fibrous material. Asthe fibrous material passes into the intake opening 47 it is acted on by the targing pins 30 of the rotor 21 and it is held back by the grip rollers 57-the peripheral speed of which is considerably less than that of the rotor-so that the pins 30 effect a combing and cleaning action on the fibrous material (particularly the crop end which is the more ditficult to clean) and thus approximately two-thirds of the length of the fibrous material is'cleaned before it leaves the grip rollers 57. Inasmuch as the root end of the fibrous material is the more easily cleaned, the beating and targing it receives on its way to the discharge end of the apparatus eifectually completes the cleaning of the fibrous material.

Along the front of the casing 35 are arranged: a plurality o'fhinged air-inlet doors '59 the opening of'which is adjustable by engagement of the doors with pivoted notched arms60 which pass through slots 61 in the doors 59. Adjacent to the lower open part of the casing 35 is arranged a suitable endless apron 62 for conveying away the dust, shive, impurities, etc, which fall to the lower part of the casing as the fibrous material is being treated.

From the foregoing it will be understood that in operation broken fibrous material or straw from breaker rolls (not shown) may be fed by conveyer 58 to the grip rollers 57 where it is given a' preliminary cleaning by the pins 30 which raise the material and pull it apart and comb it over the pins 33-which are disposed at the opening 56. After leaving the grip rollers 57 the material is picked up by the rotor 21 and by reason of centrifugal force it is thrown ina stream line against the corners of the scraping bars 46 and it is guided by the bars 40 to the recess 39 where it is thrown free of the rotor, drops down, is again picked up by the rotor, combed against the pins 33 at the rear of the casing and is then dragged by the rotor in a helical directionin consequence of the guide bars 40 and 42and contacts with the scraping bars 46 and with the teeth 33 at the front of the casing, is again freed from the rotor and drops in the recess 39, etc, until the material has made a suflicient number of revolutions to effect its cleaning by coaction thereon of the rotor and the cage 38, whereupon the cleaned material passes through the discharge opening 48 onto spout 63 and thence may pass to any suitable tow bin, not shown, freed from all woody particles, and in. an unbroken, untangled condition. The timbers 26 are preferably inclined to have the pins 30 revolve in planes substantially parallel to the planes of the bars 42.

Air is admitted through any or all of the doors 59 and it, by action of the vanes 34, drives the loosened shive and the dust from the fibrous material.

lVl1ile oneform of construction embodying the invention has been particularly illustrated and described, many changes and modifications will occur to those skilled in the art-wherefore the right is reserved to all such changes and modifications as do not depart from the spirit and scope of. the invention as defined in the appended claims.
